Play a song with the mp3 shield withe a signal received by the receiver 434

Using Arduino Audio

I send a signal with the transmitter 434, the receiver receives the signal but the mp3 shield doesn't play the music.
If I teste each one separately, they work correctly.

#include <VirtualWire.h> 
#include <SPI.h>
#include <SdFat.h>
#include <SdFatUtil.h>
#include <SFEMP3Shield.h>

SdFat sd;
SFEMP3Shield MP3player;
const int led = 12;
int resultado;

void setup() {
    vw_set_ptt_inverted(true); // Required for DR3100
    vw_set_rx_pin(13);
    vw_setup(1000);  // Bits per sec
    pinMode(led, OUTPUT);
    vw_rx_start();       // Start the receiver PLL running
    
  if(!sd.begin(SD_SEL, SPI_HALF_SPEED)) sd.initErrorHalt();
  if(!sd.chdir("/")) sd.errorHalt("sd.chdir");  
  resultado = MP3player.begin();

  if(resultado != 0) {
    Serial.print(F("Codigo de erro: "));
    Serial.print(resultado);
    Serial.println(F(" ao tentar tocar a musica"));
    
    if(resultado == 6 ) {
      Serial.println(F("Atencao: Plugins não encontrados."));
    }
  }
}

void loop() {
    uint8_t buf[VW_MAX_MESSAGE_LEN];
    uint8_t buflen = VW_MAX_MESSAGE_LEN;

    if (vw_get_message(buf, &buflen)) // Non-blocking
    {
      if(buf[0]=='1'){
   digitalWrite(led,HIGH);
   MP3player.setBitRate(192);
   MP3player.setVolume(10,10);
   MP3player.playTrack(1);
      } 
       
    if(buf[0]=='0'){
      digitalWrite(led,LOW);
    }

  }

  delay(10000);
}

Do you have DR3100? If not, take this out. In your Tx code as well:

vw_set_ptt_inverted(true); // Required for DR3100

VirtualWire takes over timer1 - do you have conflict with other libraries?

Check the virtualwire documentation - these may need to occur After the rx_start command:
vw_set_rx_pin(13);
vw_setup(1000); // Bits per sec
same on the Tx code.
